TECH FACTS – Coolant Glossary

Coolant Glossary Antifreeze: A mixture of glycol and water (typically 50:50) with a corrosion inhibitor package. An appropriate mixture balances the need for maximum heat transfer with appropriate freeze protection cold environments. Azole: These chemicals provide copper and brass protection. The two most common are MBT (Mercaptobenzothiazole) and TTZ (Tolyltriazole). Borate: a very soluble pH buffer used in […]

Mechanisms of Wear and Basic Characteristics

TECH TIP – Basic Characteristics and Mechanisms of Wear   Definition of Mechanisms of Wear. Wear is the continuous damage process of surfaces, which are usually in contact and typically in movement. It is the inevitable result of friction. The failure of a mechanical component occurs in three ways: wear, fatigue and corrosion. Among them, wear […]

COOLING SYSTEM TECH FACTS – Coolant

Coolant Coolant in its most basic form is a fluid that transfers waste heat away from an internal combustion engine. Without the proper flow of coolant, critical engine parts may degrade, deform, or even crack and fail. The cheapest and most effective coolant is usually water but it has some major shortcomings. It is corrosive […]
